Which equation represents the area of the triangle? a) a = 1 2 (ac)(ab)(sin a) b) a = 1 2 (ac)(bc)(sin a) c) a = 1 2 (bc)(bd)(sin a) d) a = 1 2 (ab)(bd)(sin a) eliminate

The correct option is A.

Step-by-step explanation:

Let the vertices of the triangle be ABC.

Draw a perpendicular on AC from B. The height of triangle is represented by the altitude from B.

Area of the triangle is

Therefore option A is correct.
